framedelta~
Description
framedelta~ computes a running phase deviation by subtracting values in each position of its previously received signal vector from the current signal vector. When used inside a pfft~ object, it keeps a running phase deviation of the FFT because the FFT size is equal to the signal vector size.
Examples
framedelta~ computes the difference between successive frames of FFT data
Arguments
None.
Attributes
Common Box Attributes
Messages
signal
The input on which the deviation will be computed.
Output
signal
For each signal vector, the first sample of its output will be the first sample in the current signal vector minus the first sample in the previous signal vector, the second sample of its output will be the second sample in the current signal vector minus the second sample in the previous signal vector, and so on.
